BOW STRUCTURING METHOD

Technical Field

The present invention relates to a structuring method for the bows being one of the equipment used for the archery and hunting, used as a hobby or used for sporting purposes.

State of the Art

The mankind used the arrow and the bow for fighting, for showing personal heroism and for obtaining food during the period until the transition from the nomadic life to the sedentary life. Turks, Huns, Romans, Brits and many other nations organized famous competitions and added such activities to their cultures and national Identities. With regard to the modem life, the use of the arrows and the bows continues in the stories regarded among the world's classics. In the archery as a sporting activity, in the shooting as a hobby and/or for decorative purposes in order to render the houses, work places, In short the living quarters, more beautiful.

Accordingly, the arrow and the bow have been used for the purposes of hunting, recreation, sporting, fighting or for decorative purposes since the beginning of the human history.

The archery sport is one of the oldest sports, wherein one equipment mandatory to use for the archery sport Is the arrow and the other Is the bow. The main purpose of a bow is to Increase the speed of an arrow shot towards a target point, avoid disturbing the direction of the arrow, avoid deviating the orientation of the arrow and transmit the push force applied by the person to the arrow. Further, the expectations from the material used in the manufacture of the bow being used are that the bow should be of lightweight, should transfer the force applied by the archer on the bow to the arrow to the maximum extent and should avoid disturbing the direction and orientation of the arrow.

The bows may be classified according to their shape and to the material used. In fact> the bows have three basic types called the recurve bows, compound bows and traditional bows _* However, in terms of the materials from which they are made, it is possible to manufacture the bows by the use of many materials such as wood, composite material, rigid plastic materials, materials with organic content, etc.

The bows manufactured from the material known as Polyvinyl Chloride (a polymer formed by the use of petroleum or natural gas and salt) are available In the market. Such bows are obtained by way of thermoformlng the molten plastic. Although they have low cost, as the primary material is of plastic nature, such bows having Inferior mechanical properties and being nondurable, fragile and prone to deformation are unpractical.

The bows made from the organic material are manufactured from the trees; fishes; the hooves, bones, horns, nerve and tendon structures of the cattle and sheep and goat; and the trunks and stems of some plants. The manufacture of such bows based on the archery culture of the Ottoman Empire involves the time consuming and demanding processes. All the properties of the bow, which is entirely manufactured from wood, encompass the physical and biological properties of the tree employed. For this reason, the organic materials are blended and used in the composite form.

There also present the bows the manufacture of which involves the process of preparing a wooden frame from the selected trees, bonding the handle and midsection made from keratlnous organic material obtained from the animals, coating with the collagen-based glue material obtained by drying and diluting with water the air bladder and palate cartilage of the mouth roof of the European sturgeon fish, shaping, drying, wrapping in horse hide and storing. Although lasting for up to two hundred years, these bows, which are quite heavy and resistant to heat and moisture and the manufacture of which takes months and even years in case of some techniques being employed, are not suitable for the archery sport. These bows, being of value in material as well as spiritual terms, are generally used for decorative purposes.

Another material employed In the manufacture of the bows comprises the polyesters with an entirely synthetic content, which are reinforced with glass fiber and/or carbon fiber. The bows made from a single metal or from metal alloys are also available in the market, but they are not preferred as a result of their being heavy, the archer's being unable to perfectly grasp the bow due to the stlckness feature and the material employed in the manufacture having a law flexibility coefficient.

However, what matters most Is the type and quality of the material used, irrespective of the type of the bow. ft is the major factor that alters the desired and intended outcome in a positive/negative way irrespective of the skill of the archer, the technique the archer is using or the experience of the archer. Consequently, the need has emerged to provide Innovation for and . to eliminate the drawbacks of the state of the art.

Object of the Invention The primary object of the invention is to Increase the use of the stress-accumulating reflex material of the bow by way of making structural changes In the bow bodies manufactured from natural materials, synthetic materials or composite materials formed by a combination of natural and synthetic materials, obtain a bow body that has greater strength as compared to a bow body manufactured according to the conventional methods by way of increasing the contact surface between such material and the frame material, and provide the arrow with speed by way of increasing the potential energy loaded by this bow in the arrow being shot. Another object of the invention is to Increase the Use of the flexibility material of the bow and obtain a bow body that is more flexible than a bow body manufacture according to the conventional methods by way Of increasing the contact surface between such material and the frame material. in order to achieve the aforesaid objects, the bow. has been separated In a way to comprise three main components wherein the duties of the materials constituting each component are Indicated below.

- The flexibility material Is obtained by using the nerves obtained from the section of. the body of the cattle and the sheep arid goat between the ankle and knee for the bows manufactured from natural/organic material or by using the materials such as glass fiber, carbon fiber, etc. for the synthetic bows. The primary function of the material is to exhibit tension force against the compression energy to prevent the bow from being broken. Likewise, the material enables the bow to close id a rapid manner thereby enabling the bow to become ready for the next shot

- As the name implies, the frame Is the basic component that constitutes the body of the bow by way of the flexibility and reflex materials being positioned/coated/absorbed on the same in an inseparable manner and that provides the strength. The wood Is frequently used for the frame in the bows manufactured from the natural/organic material wherein the maple Is preferably used for this purpose. For the synthetic bows, the frame material is usually comprised by Syntactic foam, also called the foam with hollow particles, or polycarbonate.

- The reflex material Is the material enabling. the stress to be accumulated in the bows wherein the horn material is preferably used for this purpose In the organic bows. In the synthetic bows, it is possible to use glass fiber, carbon fiber or various fabric types instead of the horn. In terms of structure, the use of rigid materials increases the strength of the bow.

Some of the glues employed to bind together the components mentioned above during the manufacture of a bow are Cega glue (a type of glue obtained from the ox nerves according to Ottoman records) or fish glue. £ega glue is made from the remaining ends of the previously ground ox nerves. The fish glue, which is more preferable, Is made from the palate cartilage from the roof of the mouth of the European sturgeon. Besides these, ft is possible to use the synthetic glues and/or apply various heat treatments to enable the components to join together. The structural and Characteristic features of the embodiments of the Invention and the advantages provided by the same will become more clearly understood from the drawings listed below and the parts In said drawings, which are assigned with reference numerals and which are explained below, and the Invention should be considered in tight of these descriptions.
